Abstract
An airflow guiding cover includes a first airflow guiding portion, a second airflow guiding portion connected to an end of the first airflow guiding portion, and a third airflow guiding portion connected to an opposite end of the first airflow guiding portion. The first airflow guiding portion is collapsible and extendable along a first direction and flexible along a second direction perpendicular to the first direction, to enable the airflow guiding cover to fit for different system layout.
Claims19
An airflow guiding cover for an electronic device, the electronic device comprising an end wall defining a heat dissipating area, a circuit board, a heat sink mounted to the circuit board, and a fan aligning with the heat sink, the airflow guiding cover comprising:
- a first airflow guiding portion configured in an accordion structure, and collapsible and extendable along a first direction and flexible along a second direction perpendicular to the first direction, the first airflow guiding portion comprising a top wall parallel to the circuit board and the first and second directions, and two sidewalls extending down from opposite sides of the top wall parallel to the first direction, wherein corresponding ends of the top wall and the sidewalls of the first airflow guiding portion are connected to the end wall of the electronic device, with the heat dissipating area aligning with an inner of the first airflow guiding portion;
- and
- a second airflow guiding portion covering the heat sink, with the fan aligning with an inner of the second airflow guiding portion, the second airflow guiding portion comprising a top wall connected to the top wall of the first airflow guiding portion, and two sidewalls extending down from opposite sides of the top wall of the second airflow guiding portion and connected to the sidewalls of the first airflow guiding portion, wherein a latch protrudes from an inner side of each sidewall of the second airflow guiding portion, to engage with the heat sink.
An airflow guiding cover for an electronic device, the airflow guiding cover comprising:
- a substantially U-shaped first airflow guiding portion configured in an accordion-like structure, and collapsible and extendable along a first direction and flexible along a second direction perpendicular to the first direction;
- a substantially U-shaped second airflow guiding portion connected to a first end of the first airflow guiding portion, a latch protruding from an inner side of each of opposite sidewalls of the second airflow guiding portion, to engage with a heat sink;
- and
- a substantially U-shaped third airflow guiding portion connected to a second end of the first airflow guiding portion opposite to the first end, a locking mechanism formed on a distal end of the third airflow guiding portion away from the first airflow guiding portion, to engage with an end wall of the electronic device.
An electronic device comprising:
- a base board;
- a circuit board mounted on the base board;
- a heat sink mounted to the circuit board;
- a fan aligning with the heat sink;
- an end wall extending perpendicularly from the base board and defining a heat dissipating area;
- and
- an airflow guiding cover for the electronic device, comprising:
- a first airflow guiding portion configured in an accordion structure, and collapsible and extendable along a first direction and flexible along a second direction perpendicular to the first direction, the first airflow guiding portion comprising a top wall parallel to the circuit board and the first and second directions, and two sidewalls extending down from opposite sides of the top wall parallel to the first direction, wherein corresponding ends of the top wall and the sidewalls of the first airflow guiding portion are connected to the end wall of the electronic device, with the heat dissipating area aligning with an inner of the first airflow guiding portion;
- and
- a second airflow guiding portion covering the heat sink, with the fan aligning with an inner of the second airflow guiding portion, the second airflow guiding portion comprising a top wall connected to the top wall of the first airflow guiding portion, and two sidewalls extending down from opposite sides of the top wall of the second airflow guiding portion and connected to the sidewalls of the first airflow guiding portion, wherein a latch protrudes from an inner side of each sidewall of the second airflow guiding portion, to engage with the heat sink.
